A series of cyclopentadienyl-iron-complexed azo-functionalized polymers were synthesized. The visible spectra of the azo dyes changed upon reaction with organometallic complexes; however, the absorption spectra of the monomers and polymers were similar. Photolysis of the organoiron polymers allowed for isolation of their org. analogs, which possessed similar visible absorbances. These polymers were subjected to photolysis in the presence of hydrogen peroxide, resulting in bleaching of the azo dye-functionalized polymers.
